Hey all. got a sore, red, swollen gum on the left side. no tooth pain or discomfort. have sinus issues though. could a sinus infection cause it?

Probably not: Your sinuses do not communicate with gum tissue around your teeth. You may have an infection that is draining, therefore no pain (no internal pressure). Please see a local dentist for evaluation.

Unlikely: Possible but unlikely. Likely cause is dental. See your dentist or oral surgeon for evaluation.

Not related: Usually, dental infection of the teeth and gums can cause sinus infection and not the other way around.

No: More likely due to tooth/teeth infection and/or gum infection. These infections require treatment. A pill won't cure, and neither will hoping the problem will self correct. Please call your Dentist.
